In the world of industrial automation and fluid control, solenoid valves are crucial components that manage the flow of gases, liquids, and other materials in various applications. Among the different types of solenoid valves, the Normally Closed (NC) solenoid valve is particularly important for systems where the default state requires the valve to remain closed until an external electrical signal activates it. These valves are widely used in industries such as water treatment, HVAC (heating, ventilation, and air conditioning), and automotive, as well as in sectors like oil and gas, chemical processing, and food manufacturing. Among the global producers, China Normally Closed Solenoid Valve Manufacturers stand out for their competitive pricing, technological innovations, and wide range of products.

Understanding Normally Closed Solenoid Valves A Normally Closed solenoid valve operates by using an electromagnet to control the opening and closing of a valve. In its default state (when there is no electric current), the valve remains closed, preventing the flow of the fluid or gas. When an electrical current is passed through the coil, it generates a magnetic field that lifts or pulls a plunger, opening the valve and allowing the fluid or gas to flow. This makes the valve ideal for applications where it is crucial to stop the flow of materials when the system is not powered or when the valve is not in use.
